Definitions

  • This invention relates to lubricating oil compositions containing a mineral base oil and an oil-soluble polyalkylene oxide compound.
  • Mineral oil lubricants such as paraffinic or naphthenic petroleum oils, have been used for most lubricating purposes. However, they have certain disadvantages such as relatively low viscosity indices over varying temperatures and high susceptibility to oxidation.
  • Synthetic lubricating oils such as those of polyalkylene oxide type have been used as substitutes for mineral oil lubricants in certain area because of their relatively high viscosity indices in comparison with mineral oil lubricants.
  • polymeric alkylene oxides containing long chain alkylene oxide moieties are substantially freely soluble in aliphatic hydrocarbon liquids and may be mixed with paraffinic or naphthenic lubricating oil bases to improve their properties such as viscosity indices, load-carrying capacities, anti-oxidative properties, wear resistances and the like.
  • a lubricating oil composition consisting essentially of a paraffinic or naphthenic or a mixture of both types of mineral oils, and 5 to 60% by weight of the composition of a polyalkylene oxide compound of the formula: wherein
  • polyalkylene oxide compounds of the above type are disclosed in, for example, U.S. Patent No. 4 302 349 to Kosswig et al.
  • this compounds are surface active agents suitable for reducing the interfacial surface tension of oily phases with respect to water.
  • the polyalkylene oxide compounds may be prepared by reacting a starting active hydrogen compound R(H)z in the presence of a basic or acidic catalyst first with a C 2 -C 4 alkylene oxide and then with a Ce-C 4 o alkylene oxide.
  • starting active hydrogen compounds include aliphatic monoalcohols such as methanol, ethanol, butanol, lauryl alcohol, oleyl alcohol and stearyl alcohol; glycols such as ethylene glycol, propylene glycol and butylene glycol; polyols such as glycerine, trimethylolpropane, sorbitol and sucrose; phenols such as phenol, bisphenol A and hydroquinone; amines such as ammonia, ethylenediamine, triethylenediamine, n-butylamine, laurylamine, aniline and toluidine; carboxylic acids such as acetic acid, maleic acid and oleic acid.
  • aliphatic monoalcohols such as methanol, ethanol, butanol, lauryl alcohol, oleyl alcohol and stearyl alcohol
  • glycols such as ethylene glycol, propylene glycol and butylene glycol
  • polyols such as glycerine,
  • C 3 -C 4 alkylene oxides examples include propylene oxide and butylene oxide. Mixtures of these alkylene oxides may also be used. Propylene oxide alone is preferable.
  • Usable basic or acidic catalyst include sodium hydroxide, potassium hydroxide, sodium acetate, sodium methoxide, boron tetrafluoride and phosphoric acid.
  • the proportions of C 3 -C 4 alkylene oxide and C 6 -C 4 o alkylene oxide relative to the active hydrogen compound are selected so that the resulting adduct has a molecular weight of 500-100,000 and the C 6 -C 40 alkylene oxide content of 15 to 60%, preferably 20 to 50% by weight of the entire molecule.
  • the reaction may be carried out at a temperature of 100 ° C to 150 ° C at a pressure below 0.59 MPa.
  • the resulting polyalkylene oxide adducts are substantially freely soluble in aliphatic hydrocarbon liquids such as paraffinic or naphthenic mineral oil bases.
  • aliphatic hydrocarbon liquids such as paraffinic or naphthenic mineral oil bases.
  • polyalkylene oxides which are soluble in both aliphatic and aromatic hydrocarbon liquids while those soluble only in aromatic hydrocarbons are known.
  • the polyalkylene oxide compounds used in the present invention may be intermixed with a paraffinic or naphthenic or a mixture of both types of mineral oils at any proportion.
  • the proportions of the polyalkylene oxide compounds ranging from 5 to 60%, preferably from 10 to 50% by weight of the composition have been found advantageous.
  • the polyalkylene compounds may improve properties of the base oils including viscosity indices, load-carrying capacities, anti-oxidative properties, wear resistances and the like while retaining inherent beneficial properties of the base oils.
  • the composition may contain conventional additives such as anti-oxidants, rust preventors and the like.
  • An autoclave having stirring means was charged with 6 parts of propylene glycol and 5 parts of potassium hydroxide and then purged with nitrogen gas. 924 parts of propylene oxide were introduced to the autoclave at a pressure of 0.40 MPa and reacted at 130°C. Thereafter, 284 parts of nonene oxide were reacted at 130 ° C. Total reaction time was 4 hours.
  • This polyalkylene oxide compound has a viscosity of 250 mPas at 25 ° C, a nonene oxide content of 22%, and a molecular weight of 1284, and is freely soluble in liquid paraffin.

  • the resulting compositions and control oils free of the polyalkylene oxide compound were subjected to a load-carrying capacity test using Soda's four-balls tester at 220 rpm. The results are shown in Table 2.
  • the polyalkylene oxide compound improved various properties of the base oils significantly.
